Trace Adkins' 12 years of sobriety ended not with a whimper, but with a drunken bar brawl ... with a Trace Adkins impersonator at karaoke night on a cruise ship. Yes, really. The country star was headlining a country-music-themed cruise, which was headed from Miami to Jamaica, when he got into a fight with the impersonator, who was performing karaoke, on Monday night. As soon as the boat reached Jamaica, Adkins got off and went directly to rehab, sources tell TMZ.

"Trace has entered a treatment facility after a setback in his battle with alcoholism," his rep confirms to People. "As he faces these issues head-on, we ask that his family's privacy will be respected." Adkins was last in rehab in 2001, after a family intervention, the Los Angeles Times reports.
